Hi Jorge, I've forwarded this bug upstream to https://bugs.freedesktop.org/show_bug.cgi?id=26418 - please subscribe to this bug report in case upstream needs additional information or wishes you to test something. They may provide a patch to try or may want you to do some additional technical debugging; there are some docs available at http://wiki.ubuntu.com/X/ to help walk you through what they ask for (and if there isn't, please feel welcome to add to the wiki as you learn.)

Jorge - also you might ping jbarnes on IRC and give him the fdo bug number.

I think I have this bug too; for a while I thought it was due to ecryptfs because it happens very frequently while I'm switch message in Mutt, and last time that was happening it was ecryptfs related, but because the screen quickly stops updating and I can use the SysRq key to reboot. I didn't have access to another computer to SSH into mine the last time this happened, but I will check when this happens again and confirm whether this is a GPU hang. I do see that CapsLock doesn't work anymore after the hang which is why I thought my system had completely frozen -- but thinking about it, it could be that the xorg events dont get delivered anymore.

@Jorge: do you still get this bug? I didn't get it in the last couple of days I've been running libdrm 2.4.18.

Hi Loic, thanks for the reminder, I missed the DRM upload in the upload changelog so I wasn't using the laptop.

I've been using it all morning and it's back to it's rock solid self. I'll resolve this here and upstream.
